Super nice! Good to have a manual in digital format.
Recipe 26: Vibromatic
Here's another use for LFOs - tremolo effects. We can fake a tremolo with Trash by using a straight shelf filter and modulating not the frequency, but the gain. Check out the Vibromatic preset. A shelf filter is sweeping up and down in gain to create the modulation in level. Not exactly how a tremolo works in a strict technical sense, but does the job really well8. You can change the speed of the tremolo with the LFO period, and the amount of the effect by moving the start and end points of the shelf filter further apart. We�ve put an old amp model on it for effect, but that�s optional� Fun thing to try: Combine sweeping of the gain with some changes in frequency or resonance to get strange hybrid phaser/tremolo/filter sounds.
Recipe 27: Reverse Wah
The general rule for wah pedals is that as you "open it up" it reveals more of the higher end frequencies. Back off and the filter sweeps down to just let lower frequencies through. Does it have it be that way? We don't think so. What if opening up the wah meant filling in the low frequencies? Instead of a low pass filter sweeping up, it was a high pass filter sweeping down? Crazy?!?! Check out the Reverse Wah preset. Play harder and you get more low end. Lighten up and the tone is restricted to just the high end. More of an �owww� pedal instead of a �wahhh� effect. Lots of fun.
Preset 28: Ratsy A
For guitarists, nothing says 80s metal like the ProCo Rat pedal. It�s also a great nasty sound for keyboards. It uses hard diode clipping to create rough symmetric clipping. Nothing soft or smooshy about this one. Give it a shot.
Preset 29: Bass Tube Overdrive
Just to make sure we touch on the idea � Trash can be very useful for adding some realism to bass and guitar patches. The Bass Tube Overdrive adds some compression, tube saturation and bass amp modeling to make a bass synth a little less synthetic.

Just as a footnote, vibrato and tremolo are sometimes confused. Vibrato is modulation of pitch or
frequency modulation, while tremolo is modulation of level or amplitude modulation. Many amps and pedals that have "vibrato" in the name are really tremolo effects. One exception was the Magnatone guitar amp. Developed in the 50s, it was the first guitar amp with real Vibrato. U.S.Patent # 2,988,706 if you're curious how they did it. Another way to do it is found in Leslie rotating speakers. These have both amplitude modulation, when the speaker turns away from you, as well as frequency modulation due to the Doppler shift of the speaker moving towards you then away from you. Same reason that a police siren sounds higher pitched as it moves towards you and drops in frequency when it moves away from you.
